Kprobes support for MIPS architecture.

This is an initial draft of Kprobes support for MIPS architecture.
It is based on a patch series submitted on CELinux mailing list
from Sony for 2.6.16 series. Since then many things changed including
APIs and file paths. So this is essentially a patch replayed on
latest series.

Please review and provide your feedback.
